Usage
DSCP levels can be assigned to specific traffic patterns in order to ensure that data packets are delivered
according to the precedence with which they are tagged. The diffserv markings are applied to the outer IP
header of every GTP data packet. The diffserv marking of the inner IP header is not modified.
The traffic patterns are defined by QCI (1 to 9). Data packets falling under the category of each of the traffic
patterns are tagged with a DSCP that further indicate their precedence as shown in the following tables:
